Abstract

Twenty-six sulfur-extended asphalt (SEA) paving projects, constructed between 1975 and 1982 in 18 states, were surveyed to measure the incidence and severity of major, visible types of pavement distress. Present condition indices were calculated for each of the SEA pavements and for each pavement in a control group of closely matched, conventional asphalt concrete pavements. Analysis of the evaluationresults indicates that the presence of 20 to 40 percent by weight of sulfur in the paving binder had no deleterious effect on the overall performance of SEA pavement but yielded not significant improvement compared with the control group. Within the limits of the analysis, the measured types of distress and their severity were not significantly affected by variation in the sulfur content of the paving binder.(A).
